Abstract: Laboratory experiments were conducted to assess the impact of sublethal doses of imidacloprid for adult aphid of F0 generation, and the impact of sublethal doses of imidacloprid on Myzus persicae was assessed by comparison of life table parameters, population trend index (I) and the interfering indexes of population control (IIPC) through the constructing of the life table of the experimental population for F1 generation. The results showed the impact of sublethal doses of imidacloprid on adult aphid of F0 generation mostly shortened longevity and depressed the total fecundity; The effects of sublethal doses of imidacloprid on F1 generation were depressing rm、R0 and λ, prolonging Td and td as well as reducing I. The values of IIPC were all less than 1. The results suggested that the sublethal doses of imidacloprid have the sustainable control function to M. persicae, and no stimulating of reproduction for M. persicae was existed.
